It took President Donald Trump less than a year to fulfill a campaign promise to end deportation amnesty for young people illegally brought into the U.S. as children. Trump announced he would nix the Deferred Action for Childhood Arrivals (DACA) program last week. According to the initiative, enacted by President Barack Obama’s executive order five years ago, recipients receive Social Security numbers and work permits in exchange for their personal information and fingerprints.

It took protesters only hours to marshal in Minneapolis upon announcement of Trump’s decision. About 1,000 people marched through downtown, then united with another group in front of the federal courthouse. The protest was peaceful and lasted about an hour.

Among the reporters on the ground following the developments in real time was WCCO’s Esme Murphy.

On Tuesday afternoon, she tweeted, “Protesters blocking traffic in downtown Mpls. by Fed courthouse.” Accompanying the text was a photo of peaceful marchers simply exercising their right of free speech.

“It’s unpleasant and unfriendly to rob the lives for which our neighbors have worked so hard to make and sustain,” another said. “Shame on you.”

Chamberlain is no stranger to protests himself. In 2016, he participated in anti-abortion rally on the steps of the Capitol in St. Paul. But the act of blocking traffic is what gets his undies in the bunch.

“1st amend does not extend to blocking traffic,” Chamberlain later clarified. He did not respond to repeated messages seeking comment.
